  2. 1. Evolutionary genomics in Corvids : – From single nucleotides to structural variants

    Author : Matthias H. Weissensteiner; Jochen B.W. Wolf; Manfred Grabherr; Kateryna M. Makova; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; evolutionary genetics; genomics; population genetics; selection; recombination; chromosomal features; colouration; insertion; deletion; inversion; crow; tandem repeat; transposable element; gene expression;

    Abstract : Heritable genetic variation is the raw material of evolution and can occur in many different forms, from altering single nucleotides to rearranging stretches of millions at once. DNA mutations that result in phenotypic differences are the basis upon which natural selection can act, leading to a shift of the frequency of those mutations. READ MORE

  4. 2. Evolutionary innovation : Early industrial uses of genetic engineering

    Author : Maureen McKelvey; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Biotechnology industry; Economics of innovation; Evolutionary Economics; Genentech; human growth hormone; Kabi; technological innovation; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Abstract : Based on an analysis of biological and economic theories of evol~tion, this dissertation first specifies evolutionary innovation and then uses it toanalyze early industrial uses of genetic engineering. Innovation refers totechnological innovation processes, i.e. series of innovative activitiesresulting in technical change. READ MORE

  5. 3. Quo vadis? Insights into the determinants of evolutionary dynamics

    Author : Alexandre Rêgo; Rike Stelkens; Dmitri Petrov; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; natural selection; selection; genetic drift; evolutionary rescue; historical contingency; adaptation; complex environments; evolutionary predictability; parallel evolution; populationsgenetik; Population Genetics;

    Abstract : Predicting future evolutionary outcomes and explaining past and current patterns of biodiversity are fundamental goals in evolutionary biology. Trajectories of evolving populations are determined by evolutionary mechanisms (natural selection, mutation, genetic drift, and gene flow) and the environment in which the populations are found.

  6. 4. Evolutionary transitions across the tree of life : Phylogenomic case studies in environmental archaea, bacteria and eukaryotes

    Author : Max Emil Schön; Thijs J. G. Ettema; Fabien Burki; David Moreira; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Evolutionary transitions; environmental sequencing; metagenomics; single-cell genomics; phylogenomics; haloarchaea; Hikarchaeia; Rickettsiales; Picozoa; plastid evolution; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Abstract : Microbes form the majority of life on Earth, but have been systematically underrepresented in historical research. The sequencing revolutions of the last two decades have completely changed the way we can study microbial genomic information, giving us the means to probe ever deeper into their evolution.

  7. 5. Evolutionary Approaches to Sequence Alignment

    Author : Marcin Bogusz; Simon Whelan; Jeffrey Thorne; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; molecular evolution; multiple sequence alignment; pair hidden Markov models; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Abstract : Molecular evolutionary biology allows us to look into the past by analyzing sequences of amino acids or nucleotides. These analyses can be very complex, often involving advanced statistical models of sequence evolution to construct phylogenetic trees, study the patterns of natural selection and perform a number of other evolutionary studies.
